[VK] This is one of the critical questions that we seek to address in a
pragmatic manner. A generalized version of this question is "What is the
difference between an information model/domain model and a terminology?"

My response to the above is:

The NCI Thesaurus is a controlled vocabulary or concept system but has an
underlying or implicit domain model/ontology. Another viewpoint would be that it
is a "degenerate" domain ontology, i.e., some one started with a
domain specific ontology for healthcare and then "dumbed" it down by removing
all the instances and mapping the classes to concepts/codes. 

Does the above make sense?
